Be it known that I, Hauom) M; MAC- CAUsLANn, a citizen of the United States, V I ,orcester, in the county of lVorcester and State of Massachusetts, have invented certain new and'useful Improvements in Aut'omobile-Signals of which the following is a specification.

This invention relates to signals adapted to he applied to automobile' and the like for signaling following vehicles as to the movements of the vehicle carrying the signal so that, likelihood of accident will be reduced.

An object of the present-invention is to: provide a plurality of arms carrying each a signal such as Stop, Back, Right Left ete., each arm being electrically actuated and controlled by the-driver of the vehicle, any particular signal being dis played instantly by simply closing a switch such as a push button or the like within convenient reach of-the driver.

A second object of the invention to provide means whereby a signal lamp will be lighted simultaneously with the display ing of any particular signal, the signal 'lamp'j will he compact in form and will he co1n-.

fiosed of a few number of simple parts which will not easily get out of order.

lVith the'above objects in view the invention consists of certain-novel details of construction and combination of parts herein after -fully described and claimed, it being understood that :various. modifications may be made in the minor details (if-construction wit-hinthe scope of'the' appended claims."'''

In the accompanying. drawings forming part ct this specifioatum :Figure 1 1s a front elevation of the device. Fig. 21s .a

'presentrinstancetwo arms 12 and 1-3-1are illustrated, theshaft 1 of-the arml) being mounted to turn in suitable bearings'lo secured to-the front and rear wall'of the easing, and the sl1a.ft:16 of thea'rnr'IS being in the nature of a sleeve which surrounds .the shaft '14. Any 'desiredmlmber of thearmsmay: be used and-each arm is'nor- "znallydield invertical position. Each arm as providedj on. its advanced facewith .a.

sign in two-parts as shown, such as Stop '-'lh clcfhatltlghtW Left or the likeythe sign-hung'displayedthrough the sightopenlugs :11 upon'thearm b ing rotated to a horizontaltposition.i

Forrotating the'aruis' to operat ve positionfI provide solenoids 17 and lsfhaving movablecores l9 and 20 which are'connected through the lnstrmuentah-ty ofihnks 21 and 2,2 to cranks 23 and 24 carried by the shafts of the. arms as. clearly shown in: Fig. 2. Upon either solenoid being energizedthe corresponding arm will be rocked into horizont-al position and the Sign carried thereby exposed by the sight openings. -For returning the arms to released position after ea'ch actuation, helical springs-25 and 26are' conneeted to the cranks 23 and 21L of the arms and to 'the'casing.

1 :At night it :isl-desn signaldisplayedi while at the sametiine to able to illuminate the displaya;light h: 'inga' distinguish-ing'color which maybe associated-with a -partlcular signal so that the color of the glowing lamp;

i ncandesce'nb lamps 27.:md cabana sin ' furthermore being of such a color as may readily be associated with the related sign, such as'a red lamp for the sign Stop, a

- green lamp for the sign Right etc. Each lamp is mechanically thrown into circuit as the related arm is moved to operative posi- .tion, and for attaining this end I provide the following mechanism:

Arranged within thecasing are brackets 29. and 30 preferably formed bf insulating material, knife switches 31 and 32 being disposed upon the outer ends of the brackets and arranged in such a manner that upon the descent of the cranks 23 and 24, the switches will be closed. This construction is shown most clearly in Fig. 3. The switches control independent circuits which actuate the incandescent lamps, and it will. be seen that when any particular arm is moved to operative position, the. related switch will be closed and the related lamp actuated. Each lamp is of ordinary construction and is equipped with the usual key switch inthe socket as indicated at 33.

in order that the lamps may be cut out duringthe daytime when not needed.

By now referring to Fig. 4 the electrical wiring for the manual control of the device may be seen. Both solenoids have a pole connected to acommon conductor wire 34 which is connected to one pole of a battery 35 or other source of electrical energy. Each solenoid has the remaining pole connected to a related push button situated within convenient reach of the vehicle driver as for instance upon the steering wheel of the automobile or the like, the connecting wires being designated at 36 and 37 and the push button at 38 and 39. Both push buttons are connected to a common conductor wire 40 which is connected to the battery as shown. In operation suppose that the driver presses the push button 38. A circuit may be traced throu h the wire 40, push button 38, wire 36, so enoid 17, and wire 34 to the battery. Whenthis circuit is closed the core 19 of the solenoid will be drawn into the solenoid and the related arm 12 moved to operative position.

By again referring to Fig. 4 it will be seen that both incandescent lamps have a pole connected to a common conductor wire 41, the remaining poles of the lamps being connected by conductor wires '42 and 43 to the common conductor wire 34 of the solenoid. A conductor wire 44 is connected to the wire 41 and to the Wire 40. As above stated upon the actuationof each arm to operative position, the related switch will he closed; consequently upon the solenoid 17 being energized, the switch 31 will be closed, and a circuit may now be traced from the .tension of said device whereb battery through the wire 40, wire 44, wire 41, lamp 27, wire 42, and wire 34 to the battery, and when this circuit is closed the lamp 27 will glow unless, as above stated, the key switch of the lamp is opened.

A signal device including a casing having a sight opening on each side of the center of one face, a shaft in. said casing, an oscillating signal arm having an inte ral sleeve surrounding said shaft and disp aying a sign in two parts, a crank arm'on said sleeve, a tension device connected to said crank arm and to said casing and normally holding said arm concealed with-in said casing, :ind means connected tosaid crank arm and serving to oscillate said arm against the to expose both parts of said'sign throng respective sight openings- 2. A. signal device including a casing having a sight opening on each side of the center of one face, a shaft in said casing, a pair of oscillating signal arms on said shaft, a.
